Updates to the U.S. Nuclear Regulatory Commission's Consolidated NMSS Decommissioning Guidance
- U.S. Nuclear Regulatory Commission, Washington, DC 20555 (United States)
In September 2003, U.S. Nuclear Regulatory Commission (NRC) staff in the Office of Nuclear Material Safety and Safeguards (NMSS) consolidated and updated the policies and guidance of its decommissioning program in a three-volume NUREG report, NUREG-1757, 'Consolidated NMSS Decommissioning Guidance' [1,2,3]. This NUREG report provides guidance on: planning and implementing license termination under the NRC's License Termination Rule (LTR), in 10 CFR Part 20, Subpart E; complying with the radiological criteria for license termination; and complying with the requirements for financial assurance and record-keeping for decommissioning and timeliness in decommissioning of materials facilities. The staff plans to periodically update NUREG-1757, so that it reflects current NRC decommissioning policy. In September 2005, the staff issued, for public comment, draft Supplement 1 to NUREG-1757 [4], which contains proposed updates to the three volumes of NUREG-1757. Draft Supplement 1 includes new and revised decommissioning guidance that addresses some of the LTR implementation issues, which were analyzed by the staff in two Commission papers (SECY-03-0069, Results of the LTR Analysis [5]; and SECY-04-0035, Results of the LTR Analysis of the Use of Intentional Mixing of Contaminated Soil [6]). These issues include restricted use and institutional controls, onsite disposal of radioactive materials under 10 CFR 20.2002, selection and justification of exposure scenarios based on reasonably foreseeable future land use (realistic scenarios), intentional mixing of contaminated soil, and removal of material after license termination (a follow-up to the LTR Analysis issue on the relationship between the LTR and the current case-by-case approach for release of solid materials). The staff also developed new and revised guidance on other issues, including the risk-informed graded approach for engineered barriers. This paper is a follow-up to a poster session and paper at Waste Management 2004, which presented the new Consolidated NMSS Decommissioning Guidance in NUREG-1757. This paper discusses the issues addressed in the current update to NRC's decommissioning guidance and explores the relationships between the issues. (authors)
